I am having trouble with GCC, in compiling G++.  The machine is a
4.3BSD Vax 11/780.  tm.h, md, etc are linked to the vax equivalents.
GCC was compiled with -g -O -munix.  

41 Augean> cd /usr/local/gnu/g++
42 Augean> cat version.c
char *version_string = "1.25.0";
43 Augean> gcc -v
gcc version 1.27
44 Augean> gcc -c -g typecheck.c
45 Augean> gcc -c -g -O typecheck.c
gcc: Program cc1 got fatal signal 4.
46 Augean> !!
gcc -c -g -O typecheck.c

Stopped

gdb> quit
The program is running.  Quit anyway? (y or n) y


Other information:  The crash appears occur after recognising the end
of the function "build_component_ref".  If one disables the suppiled
"assert.h", and fixes a swallowed semicolon problem, cc -O -c succeeds.

Hope this isnt wasting your time.  Thankyou for GDB BTW.
